I purchased a new 2009, 500cc Bullet with sidecar, from a dealer. To pass inspection here in Massachusetts, I had the shop where I had it stored for the winter, install a head and tail light. The bike was returned to me with a dead battery. The reason given, an employee had left the light on. As the bike was to be in a bike show, they gave me a jump, and the show organizer rode it to the show place, where he then charged the battery overnight, and it seemed problem solved. It wasn't. After my first ride, it died. Thinking the battery was shot, I replaced it, three times. I come to find out that the headlight alone was 30 watts, and after having the wires cut, the bike was fine. My question is, what is the correct wattage for my lights?
